  • Patent number: 10166730
    Abstract: In manufacturing a contact lens, a contact lens mould arrangement in which the engagement between the mould halves is unconstrained and at least one mould half is sufficiently pliable or flexible that during the curing of the contact lens composition at one mold half may move or flex relative to the other to define a post-cure mould cavity of smaller volume than the pre-cure mould cavity and during which the curvatures of the first and/or second mould surfaces are allowed to change provides a significantly more efficient manufacturing process and enables one mould half to be readily utilized as a blister cup for contact lens packaging.

  • Patent number: 8053780
    Abstract: In case that a conventional TFT is formed to have an inversely staggered type, a resist mask is required to be formed by an exposing, developing, and droplet discharging in forming an island-like semiconductor region. It resulted in the increase in the number of processes and the number of materials. According to the present invention, a process can be simplified since after forming a source region and a drain region, a portion serving as a channel region is covered by an insulating film serving as a channel protecting film to form an island-like semiconductor film, and so a semiconductor element can be manufactured by using only metal mask without using a resist mask.

    Abstract: The present invention is directed to molds for making packaging inserts having a pre-selected shape and a method of making the same. The shape of the mold is determined by first pre-selecting the shape of the packing insert. The shape of the packaging insert is dependent on the type of product that will be shipped. Once the shape of the packing insert is determined, the mold is then made by fabricating multiple parts, each part having a pre-selected shape. The shape of each part of the mold is determined such that when the mold is assembled, the mold forms a contiguous inner cavity having the shape (the inner cavity is the negative) of the pre-selected packaging insert. After the mold is assembled, beaded foam material is injected into the mold to form the packaging insert.

  • Patent number: 4941642
    Abstract: The invention relates to a negative mold containing a plurality of mold portions which can be detached from each other. It functions in particular for the manufacture of shapes consisting of plastic. The two mold halves enclose a molding chamber receiving the material to be shaped. In the chamber is arranged at least one insert abutting at least one projection which together form the negative for a surface depression to be produced in the shape. On the insert a fastening shank is arranged with the transition region being located in the region of the associated mold portion surface and being formed as gradation. Thereby the insert in contact with the mold half covers completely the orifice of the opening containing the shank and, in addition, projects beyond the opening edge.

  • Patent number: 4867661
    Abstract: A mold for making annular polymeric articles comprising a core having an outer contoured surface for placing a workpiece thereon, two half-molds with holes for discharging excess polymer embracing the contoured surface of the core and partially embracing end faces of the core in the course of radial displacement of the half-molds during press-forming of the article, and a means for pressure-sealing a forming cavity of the mold. The half-molds have in the area where they are joined a width equal to the length of the generating line of the core, whereas the pressure-sealing means includes two members rigidly affixed on one of the half-molds at the opposite sides thereof. Each member has at the side facing the half-molds the form of a closure embracing these half-molds in the area where they are joined, and by their shelves embracing part of the end faces of the half-molds and core during press-forming.

  • Patent number: 4822553
    Abstract: The present invention concerns an apparatus and method for thermoforming a plastic article from a sheet of plastic material heated to a predetermined forming temperature. The apparatus includes a mold having forming surfaces defining a forming cavity generally conforming to the shape of the plastic article to be formed. The heated plastic sheet is urged into contact with the forming surfaces of the mold to form the plastic article. The mold includes at least one undercut forming element moveable between an advanced position wherein the element projects into the forming cavity to form an undercut portion in the plastic article and a retracted position wherein the element is withdrawn from the forming cavity to enable the formed plastic article to be removed from the forming cavity. After the plastic article has been formed, the undercut forming element is moved to the retracted position and a stripper plate is utilized to remove the formed plastic article from the forming cavity.

  • Patent number: 4822270
    Abstract: Apparatus for molding a thermoplastic tubular product such as a bushing having an internally threaded major diameter portion and an integral truncated minor diameter portion. A mold provided with a mold shell which jointly with a two-part mold core defines a mold cavity having a shape complementary to the shape of the molded bushing. The molded bushing has an internal undercut in the form of a thread in the major diameter portion thereof. The mold core is made as a core pin and an externally threaded sleeve of greater diameter than the core pin circumferentially of a portion of the core pin. Provision is made for moving the mold elements relatively to define the mold cavity and to effectively release the core by axial compression of the molded product while exposed on the mold core to cause it to swell radially outwardly and release the externally threaded core which forms the internal thread on the molded bushing.
